14.2.Â The Web Interface to the Source Repository

It is possible to browse the files in the source
repository by using a web interface. Changes that affect the
entire port system are now documented in the CHANGES
file. Changes that affect individual ports are now documented
in the UPDATING
file. However, the definitive answer to any question is
undoubtedly to read the source code of bsd.port.mk,
and associated files.
